Principle of work of the present invention is:
The sanitary sewage that flows into from water inlet pipe enters first anaerobic zone, big solid particulate matter and suspended substance are separated by biofilter material, staying anaerobic zone top is decomposed by acidifying, after the natural separation the self-dependent potential energy of sewage,, progressively degraded through the bigger filming filter material in space with the form of plug flow by anaerobion.Through the groove of turning one's coat, this water enters second anaerobic zone, with the same process of first anaerobic zone, sewage has obtained further degraded.Anaerobion helps the degraded of high strength domestic sewage, and the mud generation is few.Because anaerobic zone has used plug flow and the technology of the groove of turning one's coat, thus the sewage of high concentration region can back-mixing to low concentration region, increased the shock resistance of purification tank.Through the water that second anaerobe filtrate handled, most of BOD has obtained reduction.And then, enter aerobic zone again through turning one's coat groove, under the aerobic microbiological effect of water on the aerobic zone biofilter material and in the active sludge, further obtain degraded.The bubble that the aeration tube (also can be aeration plate) of aerobic zone bottom takes place constantly stirs, and keeps the oxygen level in the oxygen consumption district water, to improve viability and the degradation effect of oxygen consumption microorganism.The water of handling enters the settling region after turning one's coat through dividing plate.The settling region is the hydrostatic precipitation zone after the microbiological deterioration, and some suspension active sludge that the oxygen consumption district comes obtain precipitate and separate here, and is slipped to the purification tank bottom by the scarp, returns the oxygen consumption district, increases the microbial biomass in this district.Also be convenient to simultaneously concentrate cleaning.
It is as follows to draw the various indexs of handling in the sanitary sewage process at this device of BOD by test:
The BOD of the sanitary sewage that enters is about 250mg/l, and BOD is about 100mg/l after the anaerobic zone disaggregating treatment for the first time, and BOD was about 50mg/l after anaerobic zone was handled for the second time, and it is about 10mg/l that aerobic zone is handled the back.This shows that water after treatment is well below the sewage drainage standard of country, through after the sterilization, discharge water can be used for breed, pouring, cleaning etc. again.
